| S. No | Concern area | Description of issues | Address through IoT | References |
|
| 1 | Productivity | Deadlines and targets and no backlogs allowed. Further, poor scheduling due to human error cause delay in the supply of materials that ultimately cause project delay | IoT helps to achieve readiness and efficiency through suitable sensors to estimate quantity and raise alarms or make automatic orders | [41–43] |
|
| 2 | Maintenance | Wastage of fuel and power due to poor management; handling issues, damages, and the expiration of the materials; environment conditions, humidity maintenance | Sensors deployed can provide real-time data on all issues to continuously monitor and maintain the equipment, fuel, and material | [44–46] |
|
| 3 | Safety and security | Human security agents cannot manage huge sites | IoT enables tags to help to prevent theft through real-time monitoring of locations and their movement | [39, 43, 47] |
| Risk to a workplace or entering endangered locations | Sensors can also help to identify extreme environments or dangerous locations and set alarms for taking appropriate action |
| Fatigue and distress due to long working hours affect productivity | IoT helps to monitor signs of distress such as high pulse rate and raise an alarm |
|
| 4 | Equipment handling | Tracking of equipment condition and location | IoT enables UAVs (drone) and autonomous vehicles to help to resolve the issues mentioned | [48] |
| Humans working in unsafe locations or situations | It not only improves efficiency and accuracy but also cuts costs and time |
| Access to remote locations or inaccessible sites |
| 5 | Concreting and curing | Time management of critical activities, removal of formwork, scheduling, and cycling of formwork to avoid any delay | Embedded sensors in concrete help monitor real-time gain in strength and timely removal of formwork; it also helps manage labor and formwork cost, opening traffic on time, optimization of concrete mix design, etc. | [49, 50] |
|
| 6 | Waste management | Reduce the carbon footprint of the construction site | IoT trackers help to monitor waste disposal bins, or vehicles in a cost-effective way | [51, 52] |
| Immediate cleaning of the site to create space and reduce hazards to avoid penalties from agencies |
